Seal and Sea Lion Pictures

Many people love seals and sea lions, and it's easy to see why: they’re playful, adorable, and quite photogenic. But what is the difference between seals and their cousins the sea lions?

Also, sea lions have small flaps covering their outer ears—seals do not. Try to spot these differences as you flip through the slideshow!
